Place Value
Now subtract 4 hundreds from 642. What is 400 less than 642?
242

How Many More Hundreds? If I say 300 – 200, you say 100. To say it in a sentence, you say, “100
more than 200 is 300.” Ready? 300 – 200 100 Say it in a sentence. 100 more than 200 is 300.

How Many More Hundreds? Say each answer in a sentence that tells
how many more: 405 – 305 801 – 601 650 – 350 825 – 125 999 – 299

Application Problem Max has 42 marbles in his marble bag
after he added 20 marbles at noon. How many marbles did he have before noon?
Solution
![Page 9: ADD AND SUBTRACT MULTIPLES OF 100 Lesson 5.2:. Place Value Show 1 hundred, 4 tens, and 2 ones in chips on a place value chart. Write the number below.](https://reader035.fdocuments.net/reader035/viewer/2022062320/56649d755503460f94a55290/html5/thumbnails/9.jpg)
Concept Development Problem 1 Use your place value chart and base ten
blocks. Yesterday we added and subtracted 1
hundred. Today, let’s add 2 hundreds, then 3 hundreds, and more!
How many do you see? Say the number in unit form. 1 hundred 2 tens 5 ones Show me this number with your base ten
blocks. How much do you see now? 325
![Page 10: ADD AND SUBTRACT MULTIPLES OF 100 Lesson 5.2:. Place Value Show 1 hundred, 4 tens, and 2 ones in chips on a place value chart. Write the number below.](https://reader035.fdocuments.net/reader035/viewer/2022062320/56649d755503460f94a55290/html5/thumbnails/10.jpg)
Concept Development Problem 1 How can you show this change using your
base ten blocks? Add 2 more hundreds Show that on your chart. Now I am going to add 2 more hundreds.
You do it too. Turn and talk, what will happen to the number when I add 2 hundreds?
The number in the hundreds place will get bigger by 2. The ones and tens digits will stay the same.
![Page 11: ADD AND SUBTRACT MULTIPLES OF 100 Lesson 5.2:. Place Value Show 1 hundred, 4 tens, and 2 ones in chips on a place value chart. Write the number below.](https://reader035.fdocuments.net/reader035/viewer/2022062320/56649d755503460f94a55290/html5/thumbnails/11.jpg)
Concept Development Problem 1 Add 2 more hundreds. What is 325 + 200? Say it in unit form. 5 hundreds, 2 tens, 5 ones!
![Page 12: ADD AND SUBTRACT MULTIPLES OF 100 Lesson 5.2:. Place Value Show 1 hundred, 4 tens, and 2 ones in chips on a place value chart. Write the number below.](https://reader035.fdocuments.net/reader035/viewer/2022062320/56649d755503460f94a55290/html5/thumbnails/12.jpg)
Concept Development Problem 1 If I asked you to add 3 hundreds to 450,
how could you solve that? Count on by a hundred 3 times. Change the 4 to 7 because 4 hundreds plus
3 hundreds is 7 hundreds. Let’s show that on the board using both
simplifying strategies, the arrow way and number bonds. I know many of you can just do mental math!
![Page 13: ADD AND SUBTRACT MULTIPLES OF 100 Lesson 5.2:. Place Value Show 1 hundred, 4 tens, and 2 ones in chips on a place value chart. Write the number below.](https://reader035.fdocuments.net/reader035/viewer/2022062320/56649d755503460f94a55290/html5/thumbnails/13.jpg)
Concept Development Problem 1 I can add 3 hundreds using the arrow way,
as we did yesterday.
I can also break apart the hundreds and tens with a number bond, add the hundreds, and then add the tens.
No matter which way I write it, when I add hundreds to a number, the tens and ones stay the same!
![Page 14: ADD AND SUBTRACT MULTIPLES OF 100 Lesson 5.2:. Place Value Show 1 hundred, 4 tens, and 2 ones in chips on a place value chart. Write the number below.](https://reader035.fdocuments.net/reader035/viewer/2022062320/56649d755503460f94a55290/html5/thumbnails/14.jpg)
Concept Development Problem 1 Now it’s your turn. In your notebook, solve
147 + 200. Show me your board when you have an answer. 147 + 200
100 + 47
100 + 200 = 300300 + 47 = 347
+ 200147 347
![Page 15: ADD AND SUBTRACT MULTIPLES OF 100 Lesson 5.2:. Place Value Show 1 hundred, 4 tens, and 2 ones in chips on a place value chart. Write the number below.](https://reader035.fdocuments.net/reader035/viewer/2022062320/56649d755503460f94a55290/html5/thumbnails/15.jpg)
Concept Development Problem 1 Try these: 276 + 300 382 + 400 400 + 516
![Page 16: ADD AND SUBTRACT MULTIPLES OF 100 Lesson 5.2:. Place Value Show 1 hundred, 4 tens, and 2 ones in chips on a place value chart. Write the number below.](https://reader035.fdocuments.net/reader035/viewer/2022062320/56649d755503460f94a55290/html5/thumbnails/16.jpg)
Concept Development Problem 2 Now, let’s subtract 2 hundreds, then 3
hundreds, and more! How many do you see? 725 Say it in unit form. 7 hundreds 2 tens 5 ones How many do you see? 5 hundreds 2 tens 5 ones
![Page 17: ADD AND SUBTRACT MULTIPLES OF 100 Lesson 5.2:. Place Value Show 1 hundred, 4 tens, and 2 ones in chips on a place value chart. Write the number below.](https://reader035.fdocuments.net/reader035/viewer/2022062320/56649d755503460f94a55290/html5/thumbnails/17.jpg)
Concept Development Problem 2 I am going to subtract 2 more hundreds.
Turn and talk: What will happen to the number when I subtract 2 hundreds?
The number in the hundreds place will get smaller by 2. The number will get smaller by 200. It will be 325 because 5 hundreds minus
2 hundreds equals 3 hundreds. The other digits stay the same.
What is 525 ─ 200?
![Page 18: ADD AND SUBTRACT MULTIPLES OF 100 Lesson 5.2:. Place Value Show 1 hundred, 4 tens, and 2 ones in chips on a place value chart. Write the number below.](https://reader035.fdocuments.net/reader035/viewer/2022062320/56649d755503460f94a55290/html5/thumbnails/18.jpg)
Concept Development Problem 2
What is 525 ─ 200? 325 Say it in unit form. 3 hundreds 2 tens 5 ones Let’s subtract 3 hundreds from 582. Take
a moment and work on your place value chart to solve 582 – 300.
![Page 19: ADD AND SUBTRACT MULTIPLES OF 100 Lesson 5.2:. Place Value Show 1 hundred, 4 tens, and 2 ones in chips on a place value chart. Write the number below.](https://reader035.fdocuments.net/reader035/viewer/2022062320/56649d755503460f94a55290/html5/thumbnails/19.jpg)
Concept Development Problem 2
We have an extra simplifying strategy when we are subtracting. We can count up from the part we know.
What is the whole? 582 What is the part we know? 300
![Page 20: ADD AND SUBTRACT MULTIPLES OF 100 Lesson 5.2:. Place Value Show 1 hundred, 4 tens, and 2 ones in chips on a place value chart. Write the number below.](https://reader035.fdocuments.net/reader035/viewer/2022062320/56649d755503460f94a55290/html5/thumbnails/20.jpg)
Concept Development Problem 2
How can we show the missing part with an addition problem?
We can use the arrow way, counting first by either tens or ones. Try it with a partner.
Starting at 300 you can add 2 hundreds first and then 82, or add 82 first and then add 2 hundreds.

Concept Development Problem 2
Let’s try again: 620 – 400 541 – 200 797 – 300
